# ldivide, .\

Left array division

## Syntax

• `x = B.\A` example
• `x = ldivide(B,A)`

## Description

example

````x = B.\A` divides each element of `A` by the corresponding element of `B`. If `A` and `B` are arrays, then they must be the same size.If either `A` or `B` is a scalar, then MATLAB® expands the scalar value into an appropriately sized array.```
````x = ldivide(B,A)` is an alternative way to divide `A` by `B`, but is rarely used. It enables operator overloading for classes. ```

## Examples

### Divide Two Numeric Arrays

```A = ones(2, 3); B = [1 2 3; 4 5 6]; x = B.\A ```
```x = 1.0000 0.5000 0.3333 0.2500 0.2000 0.1667```

### Divide a Scalar by a Numeric Array

```C = 2; D = [1 2 3; 4 5 6]; x = D.\C ```
```x = 2.0000 1.0000 0.6667 0.5000 0.4000 0.3333```

## Input Arguments

### `A` — Numeratorscalar | vector | matrix | multidimensional array

Numerator, specified as a scalar, vector, matrix or multidimensional array. If `B` is an integer data type, then `A` must be the same integer type or a scalar double.

Data Types: `single` | `double` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint32` | `uint64` | `duration`
Complex Number Support: Yes

### `B` — Denominatorscalar | vector | matrix | multidimensional array

Denominator, specified as a scalar, vector, matrix or multidimensional array. If `A` is an integer data type, then `B` must be the same integer type or a scalar double.

Data Types: `single` | `double` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint32` | `uint64` | `duration`
Complex Number Support: Yes

## Output Arguments

### `x` — Solutionscalar | vector | matrix | multidimensional array

Solution, returned as a scalar, vector, matrix or multidimensional array. If either `A` or `B` are integer data types, then `x` is that same integer data type.
